DIE FOR FOIRTVIING` EDBLE PASTES.

Application filed August 19, 1911.

To all whom t 'may concern Be it known that I, KARL GAMMEL, a subject ofthe Emperor of Germany, residing at Cleveland, in the county of Cuyahogaand State of Ohio, have invented certain new` and useful Improvements inDies for Forming Edible Pastes, of which the following 1s aspecification.

In the manufacture of edible pastes, such as macaroni, it' is necessaryto form the product with a hollow interior. This is accomplished byforcing the paste through a form provided with openings having pinstherein under very heavy pressure. These pins must be elastic, so thatthey will not readily break under pressure, but they must besuiliciently strong so that they will not bend, and they must befastened securely so that they cannot be pushed to one side or workloose. Heretofore great difficulty has been experienced in securingthese pins in place so that they will operate effectively, and at thesame time permit the form to be properly cleaned. Among the variousconstructions heretofore employed the simplest form has been vto bendapiece of wire in U-shape over the passage, and fasten thesame to holesdrilled in the form. 1t has also -been customary to solder the pin tothe form.

The primary object of my invention is to provide a. construction wherebythe pin `shall be securely held against displacement and at the sametime will always remain properly centered.

A further object of my invention is lto provide a construction whichwill permit the pin to be readily removed so that both the pin itselfand the form can be thoroughly cleaned.

A further object of my invention is to provide a construction which'willpermit the largest possible number of passages to be provided in a formof given area, so that the maximum quantity of goods may be producedfrom a single press.

The various other objects of the invention will be more fully set forthin the following description of apparatus embodying my invention, whichconsists in the new and novel features of construction and combinationsof parts hereinafter set forth and claimed.

tion of the same showing different means for securing the die in place,and also the means for removing the same from the press when desired.Fig. 3 is a bottom view of the press shown in Fig. 1. Fig.I l is across-sectional view through a portion of the die showing the positionof the pins. Fig. 5 is an enlarged detail sectional view showing one ofthe passages in the die and the seat formed therein for the pin. Figs. 6and 7 are front and side elevations respectively of the pin. Fig. 5represents a cross-section of the pin on the line 8-8 of Fig. 7. Fig. 9is an enlarged plan view of a portion of the die showing the pins inplace.

Referring to the drawings the press 1 which may be of any well knownconstruction, is provided with a plunger 2 which forces the paste, suchas macaroni paste 3 through the die fl. The die is supported in thepress preferably upon a shoulder 5 either formed integral with the pressas shown in Fig. 2 or, formed by a separate sleeve of bushing 6 as shownin Fig. l. The die is supported in any suitable manner as by the braceor braces 8. Thedie is also provided with a threaded Socket 9 whichpermits the insertion of a suitable handle 10 so that it can be removedfrom the press if desired. rlhe die is provided with a plurality ofpassages for the paste. Said passages are preferably cylindrical insection throughout a portion of their length as at 11 and graduallytaper, and are section as at l2 throughout the remainder of theirlength. A shoulder 14 is formed in the die at the point where thetapered portion of thepassage begins.

Preferably the top of the cylindrical portion of the passage is slightlyflaring as indicated at 15. he pin comprises two segments 16 connectedby a transverse web 17 which is beveled at its top to form an edge 18.The stem or pin proper 19 is formed integral with the web and extendsbelow the retaining segments. Preferably the contour of the stem iscontinued substantially throughout the length of the web. The topportion of the segments are also beveled to a thin edge.

fn operation the bottoms of the segments, which are squared, seat uponthe shoulder le and hold the pin against downward displacement. Thepaste is forced into the openings in the die and into contact with Y"approximately conical in the sharp edge of the connect-ing web 17, whichis preferably arranged below the Haring mouth of the cylindrical portionof the opening. This edge separates the portion of the paste, and thecontinued pressure forces the two parts through the passages which areformed on both sides of the web between the wall of the die and theportion of the pin which is cut away between the two segments. As thepaste is forced through the conical portion of the die opening, the twoedges are Jforced together around the depending stem forming the centralopening or passage in the macaroni.

By means of this construction the pins are secured to the die in such avway that they cannot become displaced or get oit center, and at the sametime the pins can be readily removed for vthe purpose of cleaning thedie. This construction permits a relatively large number ot openings tobe made in a given die area as the adjacent rows of openings can bestaggered. This construction also permits a much greater pressure to beput upon the press than the various other form of pins heretoforeemployed and thus increases considerably the capacity of the die. Itwill be noted, also, that the pins can be cut out of drawn rods, thusreducing the cost yoi manufacture.

It is obvious that various other changes and modifications within theskill of the mechanic may be made in the details of the constructionherein shown and described without departing Yfrom the spirit of theinvention, provided the means set forth in the following claims beemployed.

1 claim as my invention 1. A. die for forming edible pastes, providedwith a plurality of openings having their 'upper portions approximatelycylindrical in section and their lower portions conical in section, anda. shoulder between said cylindrical and conical portions, of a pinsupported in said openings comprising segments seating upon saidshoulder and extending part way around said openings, a web connectingsaid segments intermediate. the ends thereof and a stem formed integralwith said web.

2l A die for forming edible pastes having openings therein comprising anapproximately cylindrical porton and an approximately conical portion,of a pin comprising segments engaging in and extending part way aroundsaid cylindrical portion, a web connecting said segments intermediatethe ends thereof and a stem formed integral with said web and projectinginto the conical portion and arranged axially thereof.

3. A die for forming edible pastes having openings therethrough, andhaving a shoulder formed in the wall of said openings, of a pinsupported on Said shoulder and comprising a web beveled at its upper endto form a cutting edge and having a cylindrical stem formed integraltherewith and depending below said shoulder, and means secured to saidweb and extending part way around said openings for centering said stem,said means having their greatest cross section of material disposedadjacent their connections with the web.

4. A die for forming edible pastes, provided with an openingtherethrough, and having a shoulder formed in the wall of said opening,of a pin supported in said opening comprising a web extendingdiametrically across said opening, segments formed integral with saidweb seating upon said shoulder, and engaging part of the wall of theopening, leaving the other part of the wall open for the free passage'of the; paste through the opening, and a stem formed integral with theweb and extending below the shoulder and being of substantially thesarge diameter throughout the length of the we 5. A die pin for use withan edible paste die plate, comprising a stem, a pair of webs extendingdiametrically from opposite sides of said stem, the outer edge of eachweb being enlarged to form a pair of spaced apart seating members forthe pin.

6. A die for forming edible pastes provided with an openingtherethrough, a die pin removably positioned in said opening below thetop thereof, .the portion of the opening above said pin beingsubstantially cylindrical and having a Haring mouth above the top of thepin, said pin including a stem, a transverse web and laterally eX-tending centering members at opposite ends of saidy web, the upper endof said stem, web and centering members being beveled whereby the pasteis fed easily through the opening and about the stem without meetingintercepting shoulders.

A die pin for use with an edible paste die plate comprising a stem, apair of webs extending diametrically from said stem beveled at their topto form a cutting edge and centering segments 4forming the outer end ofeach of said webs having their top portions beveled.
